I took the “first person shooter” sample project, turned off mobile HDR and deleted the postprocess object from the scene, and was still getting <10fps on a 2012 Nexus 7.
After minimizing the scene even further, I’m “up to” 20fps most of the time, but still dropping to <12fps on this ridiculously simple and empty scene:
The internet claims this is running a Tegra 3 with 12 cores at ~400MHz / core, which seems like it should be plenty of computing power for this ‘almost empty’ scene. What am I doing wrong? Is UE4 just not ready to run on tablets? Is there a plan to get to reasonable performance, and if so, what tablet should we be using for development in the meantime?
